are these available for sale ?

take care Alberto

Hi Alberto,

Will be, but a bit to go yet. The 67 appears to work ok but a bug exists in the card read that I haven't sorted yet. If you consider the complexity of PIC machine code emulating HP microcode and the CRC chip while trying to capture data as the card whizzes through the reader... :-)

Anyway, maybe I'm looking at the problem but can't see it so I put it aside for a bit and I'll have a go at the 65 for awhile.

cheers

Tony
